- quently of the so-called ring mount type,

that is it comprises a ring-like memberhaving brackets extending outward and back ward therefrom to support the motor of the fan. f

The fan blades are rotatedwithin the area defined by the ring, which ring alsoserves as a support for mounting the fan in the panel.

Panels of this type are subject to two general objections, the first of which is overcome o by makin the anel adjustable. -It the panel is not a justa le, a large number of slzes must be carried in stock so that the ventilating means may befit into the Various sizes of windows encountered in residences and the like.

Panels of this type are subject to further criticism that the solid nat-'ure of the su porting panel of the Ventilating means blocks o a goodly portion ofthe window space with 3 the consequent darkening of the room in which the device is employed.

In lmy present invention I have Aovercome both of these objections, first by making the panel upon which the fan'is mounted adjustable as to length so that it may be accommodated into the various size windows encountered in residences.

I have furthermore made the panel of transparent material, preferably glass, so that its insertion ina Window does not obstruct the entrance of light throughthe window and consequently does not darken the room in which 'the device is used. In my Patent No, 1,784,234 issued December 9, 1930 I disclose a similar glass panel capable of being adj ustably mounted in a window frame in the manner hereinafter described.

`In my'l copending' application, Serial No. 289,573,'filed June 30, 1928, I disclosed aventilating 'means in which ,an adjustable panel 1929. Serial No. 380,003.

was adapted to be mounted in-a window, into the space immediately above the lower sash of the window.

This construction permitted the upper sash of the window to be operated in a normal manner, so that the window could be fully closed during stormsl and the like, without lis particularly objectionable since it makes it extremely difficult for the housewife to clean the inside surface of the upper sash as well as restricting `the'opening that it is pos-l siblley to obtain by adjustment of the lower sas In my present invention I have provided a new and improved Ventilating means which overcomes this objection b providing a mounting which permits adjustment of the I Ventilating means in and out of the window, that 'is permits mountin means with itsV panel paral el to the plane o the ventilatin the window sash, and further permits adjustment of that panel at right angles toits plane and to the plane of the window sash. This adjustment can be made without' devmounting the Ventilating means from thel window. By this arrangement the ventilating panel can be drawn inward into'the room out of the track of the lower sash, thereby permitting that sash to be raised to its full extent for cleaning or any other desired purposes.

In the preferred embodiment of the invention the glass panel and its supporting frame is formed as a standard unit o lengths adapted to fit it into the average window encountered in residence and the like. The panel is arranged to'be sup Orted ina flanged mounting bracket whic engages the upper iand lower surfaces of the panel frame and which are adjustable lengthwise of the frame to compensate for slight diierences in the width ofthe windows in which the devce is to be mounted. These brackets may be madefn Ido varying lengths' so that the amount of adjustment lengthwise of the panel can be varied to suit the varied conditions encountered.

The mounting brackets are provided with flanges depending at right angles to the plane of the Ventilating panel, and slots-are provided in these flanges.

The vpanel is mounted in the window by a plate attached to the window frame on the inside of the track in which the lower sash operates. vThese plates fit between the window frame and the flanges of the mounting brackets, and conta-in threaded openings into which thumb screws are registered, those thumb screws projecting through transverse slots in the flanges of the mounting brackets.

By this arrangement, the panel is supvorted rigidly in the window, and can bead- ]usted'in and out over the. track in -which the lower sash slides by loosening of the thumb screw and sliding the flanges of the mounting bracket thereon. The panel mounting arrangement of the present invention is also shown in my copending application which has now issued as Patent No. 1,784,234.

Preferably the panel is set so that it lies just inside of the upper sash of the window when that sash is in its upper-most position, so that the sash maybe freely raised and lowered without striking against or being interfered with by the Ventilating means. This permits the upper sash to be ,tightly closed when storms are encountered.

By this preferred adjustment. of the position of the Ventilating panel the lower sash is limited in its movement as heretofore,lhow ever in instances where it is desired to open the lower sash to its fullest extent, the ventilating means can be backed into the room out of the path of the lower sash by loosening the thumb screws and sliding the flanges of the brackets thereon. The weight of the panel and fan mounted on it is at all times supported by the thumb screws even when they are loosened so that lateral adjustment of the panel in a direction at right angles -to the plane of the window sash can be easily and conveniently made.

.K In the preferred embodiment of my invention I employ a fan of the ring mounting type, and support that fan in the framework of the'transparent panel so that it is supported ventirely free of the glass or other transparent. material used in the panel. 'That is, the frame work of the trans arent panel serves as a mounting support or the ring of the fan mechanism, and instead of being supported on the glass, that ring serves as a support for the glass or other transparent material of which this panel might be constructed.

. This construction rigidly mounts vthe fan mechanism to the panel and eliminates the danger of the fan falling and being damaged should the transparent material in the panel become broken.

Now to acqua-int those skilled in the art with the teachings of my invention, reference is made to the accompanyin drawings in which I have illustrateda preerred embodiment of it and in which;

Figure 1 is an elevation view of the ventilating means mounted in a window;

Figure 2 is a cross-sectional view taken along the lines 2-2 of Figure 1 with thecentral portion broken away;A

Figure 3 is an elevation view of the transparent panel and its frame with the fan mounted thereon;

Figure 4 is a perspective view of a portion of the mounting bracket showing the details of its construction;

Figure 5 is a cross-sectional view taken along the lines 5-5 of Figure 3, and

Figure 6 is a cross-sectional view taken substantially along the lines 6--6 of Figure 3. i

By reference to the drawingsl in more detail it will be seen that the panel 1 is supported in the one end of the rectangular framework 2, and that the fan indicated generally at 3, is supported in/the center of this framework. A second panel 4 is mounted in the framework 2, on the opposite side of the fan mechanism 3.

This assembly therefore comprises a unitary structure consisting of a generally rectangular panel haviilga fan mounted opposite a central opening in the panel. The framework indicated enerally at 2 consists of a rectangular mem r 6 having a flange 7 disposed at its outside edge at right angles to the main part of the frame. A second rectangular member 8 is tted within the rectangle dened by the extreme edge of the flange 7, and held onto the member 6 by screws 9 projectingl through the member 8 and registering with threaded openings in the bosses 1() attached to the inside surface of the member 6. These bosses may be attached by soldering, welding or any other preferred method.

The member 6 and 8 and the flange 7 on the member 6 together define a framework of U shaped cross-section, the o en end of the U being disposed inawardly o .the frame.

vThe ring of the fan 3 is supported in this framework by metallic members 12 which are supported in the framework by screws 11 projecting through the member 8 into threaded openings in the members 12. There are two of these members 12, .one disposed in the upper sectionpof the frame 2 and one in the lower section, both being centrally located in their respective sections. yEach member 12 is supported in the frame by two screws 11, so that the rings of the fan can thereby be rigidly supported in the frame.

The fan 3 which is preferably of the type the ring20 to the motor support cap 22.

Preferably the ring 20 and the spider arms 21 and motor 'support cap 22 are cast as an integral unit,'preferably aluminum althou h brass yor other suitable material might substituted therefor. The ring 20 is provided with a shoulder 23 which lits against the innermost edge 0f the mounting member 12.

To attach the ring 20 to the mounting member 12 an auxiliary ring 24, containing the flange 25 and the threaded openings 26, is tted on the op site side of the member 12 and the screws 2 project through the member 20, the member 12, into the threaded opening 26 of the member 24 to attach the fan to the framework.

The shoulders 23 and 25 when buttedtogether form a rectangular slot in the periphand 24 of the fan mounting so that the panel members 1 and 4 are-prevented from coming in contact with these metal, members.

-These soft spacing members 30 to 33, inclusive, may be made of cork, felt, ber or any other preferred relatively soft material, their purpose being to cushion the glass panel members 1 and 4 to prevent them coming in Contact with the metal framework and to prevent breakage of the glass due to expansion and contraction of that framework with temperature changes and the like. l 'It will be noted in Figure 2 that the frame member 8 is disposed on the outside of the window and the frame member 6 on the inside. By this arrangement, no screw heads the color scheme of the room in which it is used, the smooth surfaces of the Aframe facilitating this operation.

The unit so constructed is rigid yet sui- `ciently light in Weight'topermit it being easily handled. The fan is supported on the framework independently of the glass panel 5 members so that the assembly may be made 'the window frame.

in the factory and shipped to-the customer without danger of breaking the glass panel during shipping.

To mount the panel '2 in the window of a residence, and to provide for adjustment of the length of this panel to meet the width of the window in which it is tobe mounted, I4

have provided mounting brackets 40 and 41 which are identical in every respect and which are disposed on opposite ends of the panel member 2. v i

The bracket 40 comprises the flat face 44 which is adapted to fit on the inside face of the panel member 2. This face 44 has the rib 45 vformed in it to stiii'en it.

At the top and bottom edges of the face 44, a flange 46 is projected at right angles to the plane of the face 44, that ange terminating in an upwardturned edge 47 disposed parallel to the plane of the face 44 and at right angles tothe ange 46. These flanges form a C clamp-like member which fits over the top and bottom edges of the' panel 2, supporting that panel in the bracket'.

This support permitsthe lbracket member 40 to be slid along in a plan'e of the panel 2.

The bracket member 4Q-is also provided with a fiange portion 48 disposed at right angles to the plane of the face 44.` This member 48 is provided with a plurality of slots 49 disposed also at right angles to the plane ofthe face 44. l

The brackets 40 and'g41 are attached tothe fan supporting panel by placing the face 44 on the inside face of the panel w1ththe flange 46 engaging the top or bottom edge of the panel and the projection 47 engaging the outside face of the panel adjacent that edge. The

corresponding ange and panel on the opposite ends of the brackets, not shown, engage .the opposite edge of the panel in a similar manner. The anges 48 projectinward from the inside face of the fan supporting panel 2 to mount the device in a window.

The panel is adjusted to the correct length to fit into. the window by sliding the brackets 40 and 41 along on the panel so that the face 44 projectsbeyond the end of the panel 2 suiiiciently to cover the space intervening be'- tween the ends of that panel and the sides of len h can be fitted into any window likely to e encountered .in residences. With. the panels 2 available in a few standard' sizes and the brackets 40 and 41 available in several sizes interchangeable with the various panels only a small stock of parts will bel required to fit the ventilator into any one of the vvarious size windows encountered.

To facilitate mounting the ventilator in a window I have provided the mounting plate which comprises a rectangular metallic bar perforated with holes 51 which are countersunk to permit attaching the bar to the frame of a window with ilat head screws which when turned up tight will be flush with the face of the plate. The plates 50 are also provided with threaded holes 52 which are spaced to register with the slots 49 in the mounting flange 48 of the bracket.

As will be best seen in Figures 1 and 2 the mounting plates 50 are attached to the inside window stop 54 preferably by ilat head wooden screws, not shown.

These plates 50 are attached to the stop 54 at a point suiiiciently far from the inside face of the lower sash 57 to permit the panel 2 to clear that face of the sash when the ventilator is drawn in to itsfullest extent.

The Ventilator is mounted upon the mounting plate 50 thumb screws 53 are projected through the .slots 49 in the mounting flange 48 and into the threaded openings 52 in the mounting plate 50. Preferably two thumb screws are provided at each end of the ventilating panel, one near the top and one near the bottom edge of it.

After the thumb screws 5 3 have been inserted `and before they are tightened up the position of the ventilator can be adjusted by moving the panel in and out, the thumbscrew 53 sliding in the slot 49 to permit this adjustment. After the panel has been positioned in the desired location, the thumb screws 53 are turned tight to securely lock the panel in place.

Preferably the ventilator is adjusted in the window so that the outside face of the panel 2 is disposed just inside of the inside face of the upper sash 56 of the window, that is with the ends of the panel 2 disposed in the plane of the parting stops which define the inner edge of the groove in which the upper sash runs. This location of the ventilating panel permits the upper sash to Abe raised and lowered in the usual manner without any interference from the Ventilating panel.

In Figure 2, by the solid lines I have indicated the maximum outward position to which the Ventilating panel can be adjusted. In this position the panel is disposed over the upper surface of the upper sash, which of course must be lowered, and the sash cannot therefore be closed without readjustment of the position of the Ventilating panel.

The dotted lines in Figure 2 indicates a maximum inward position to which the ventilating panel can be adjusted. It will be noted that this is inside of the inside face of the lower sash 57 so that that sash may be raised or lowered to its fullest extent without interference from the Ventilating panel.

This inside adjustment of the ventilator permits the full raising and lowering of the window sash, a feature which is particularly advantageous when it is necessary to wash the inside surface of the glass in the window sash. Heretofore this operation has been dillicult where Ventilating panels were installed in the window since those panels did not permit the lower sash to be raised complet-el to the top of the window and frequent y did not permit the upper sash to be completely closed.

When the thumb screws 53 are loosened to permit lateral adjustment of the Ventilating panel in the window the weight of that panel is still supported by the mounting plates 50 and the thumb screws 53 so that this lateral adjustment may be easily made.

Ventilating means constructed in accord-` v ancewith the teachings of my invention presents a pleasing appearance both from the inside and the outside of the room in which it is to be used. The transparent panels of 'the ventilator permits its use in a window without blocking out an appreciable amount of light admitted to the room through that window.

While I have illustrated a'preferred embodiment of my invention, I have done so by wfay of example only as there are many modifications and adaptations which can be made by one skilled inthe art without departing from the teachings of the invention.
